How should story progression work in the sims

I think there should be two options, "Full Range" and "Limited"

Full Range means that any non played household progresses without our input. Limited means that the game won't touch Favorited households but everything else is fair game. Then have an in-game way to effect those sims lives (I personally only play one household but then like controlling the households of their friends and family. I'd love a way to do this without actually going into their household then bouncing). I'm thinking something along the lines of interactions like "Suggest hooking up with", more often than not the date will go well and the sims you hooked up will start dating although there should be a chance of it going poorly. Then you can do things like suggest moving in together, getting married, having kids, etc (although I'd word it to be more casual sounding, for storytelling sake).

This is a little more outlandish and I'm not sure how viable it is but I think the game should run some kind of algorithm in the background that determines how sims spawn and do things autonomously (like throw events and such). Like if you go to the library, sims with the bookworm/creative/genius/geek trait should spawn there more often. Maybe have rowdy sims show up every once in a while to cause drama. Nightclubs have tons of outgoing/romantic/dance machine sims. Sims with the party animal/any wealth/friend of the world aspirations or the outgoing/dance machine traits should throw parties that you can get invited to. Maybe shyer sims can throw friendly hangouts that have fewer sims there. For drama, I think there should be something that decides events like "oh, this couple got into a fight today, while they are mad at each other it's easier to begin an affair with one. Oh, this couple's on a date, while they are out they won't come over when invited." The more it can fundamentally change a household (like a divorce) the less likely it is to happen with more criteria for the game have this even happen. I personally don't care much about promotions and don't want every sim to get to the top of their career obviously so I'm thinking of having a cap on the number of levels they can go but if they have an aspiration (such as wealth) or a trait (like ambitious) they can go higher. I also think the game should take into account traits when assigning jobs. Again, I'm not sure viable all that is though. It may cause performance issues to have all that going on in the background
